**Note**: Current (as of r35608) DIR-**825**-C1 builds work on DIR-835-A1, but LED config is not quite right and they will all be turned off by default. Wireless output on this build is also maxed out by default and may need to be turned down (especially the 2.4 GHz band, which is putting out 501 mW).

Flash **DIR-835-A1** "​factory"​ OpenWrt image file (e.g. openwrt-ar71xx-generic-**dir-835-a1**-squashfs-**factory**.bin) via D-Link firmware upgrade in web interface. ​*NOTE* the process completion is not obvious so give plenty of time and do not be confused as the LED power light will end up being AMBER instead of GREEN as on stock firmware; LED functionality can be adjusted through 'LUCI > System > Led Configuration'​.

Make sure your PC obtains a new IP address from DHCP (or use static) after installation. Initial connection must be over ethernet (you should flash over ethernet anyway).|

*Telnet to 192.168.1.1 and set a root password, or browse to http://​192.168.1.1 if LuCI is installed. ​Trunk builds will require you to manually install ​the Luci web interface ​(see [[doc/​howto/​luci.essentials]]). __WiFi is disabled by default__ as well, as it is with most other OpenWrt builds. ​

This router also supports D-Link'​s recovery mode, which can be used for initial flash or recovery. See this D-link forum post for details: http://​forums.dlink.com/​index.php?​topic=44909.msg163599#​msg163599

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

Please check out the article [[doc:techref:Flash Layout]]. It contains an example and a couple of explanations.

This router supports D-Link's recovery mode, which can be used for initial flash or recovery after a failed flash. Note that this is different than OpenWrt'​s failsafe mode. See this D-link forum post for details: http://​forums.dlink.com/​index.php?​topic=44909.msg163599#​msg163599
